What needs to be considered for ICTS?

The ICTS is being introduced to improve how HMRC assesses transfer pricing risk. Traditional transfer pricing documentation, such as a local file, explains the commercial and economic basis for related party transactions. The ICTS is different because it gives HMRC structured data that can be reviewed, compared and risk-assessed more easily.

ICTS Requirements may include:

• Related party counterparties

• Transaction categories

• Jurisdictions involved

• Transfer pricing methods

• Profit level indicators

• Margins or mark-ups

• Income and expense amounts

• Financing arrangements

• Permanent establishment dealings

• Whether the UK entity is the tested party

Key Benefits of the ICTS in Transfer Pricing

The International Controlled Transactions Schedule helps HMRC and multinational groups focus on the quality, consistency and reliability of transfer pricing data. It increases transparency around cross-border related party transactions and encourages businesses to maintain stronger documentation and governance.

Improves Transfer Pricing Governance

The ICTS encourages businesses to map their international controlled transactions more clearly. This helps groups understand which entities are involved, what transaction types exist, how pricing is determined and whether the supporting documentation is up to date.

Supports Data-Led Risk Assessment

HMRC will be able to use ICTS data to identify transfer pricing risk more efficiently. This may help reduce unnecessary enquiries into lower-risk businesses while allowing HMRC to focus on arrangements where the data suggests a higher risk of transfer pricing adjustments.

The ICTS should be consistent with the UK local file. If the local file describes one transfer pricing policy but the ICTS shows different margins, counterparties or transaction values, this may create audit risk. Preparing both together can help reduce inconsistencies.

Strengthens Local File Consistency

Many businesses do not currently hold intercompany transaction data in the format HMRC may require. Preparing for ICTS can help identify gaps in accounting systems, transaction coding, intercompany agreements and transfer pricing processes before filing becomes mandatory.

Improves Transparency and Governance

Increases HMRC Enquiry Readiness

A well-prepared ICTS can help businesses demonstrate that their transfer pricing arrangements are understood, documented and monitored. This can be important where HMRC reviews management fees, royalties, financing, cost-plus arrangements, permanent establishments or year-end adjustments.

By centralising development or service activities and sharing costs under a CCA, multinational groups can reduce inefficiencies caused by duplicated efforts across entities. This leads to better resource utilisation, lower overall costs, and a more coordinated operating model.
